You should solve it in the following order.

1. Be familiar with your board and audio CODEC.

2. Write or get a module to drive the audio CODEC. Use it and understand it.

2. Choose between a pure hardware solution or a Nios II based solution.

3. If you have choosen a pure hardware solution there is a lot of stuff to study about fft implementation: Altera core, own core, open core.

4. If you have choosen a Nios II based solution you must connect your audio CODEC module as an slave peripheral. Internet is full of C language based FFT implementations.
